    Boehm-Demers-Weiser Garbage Collector

    Boehm-Demers-Weiser Garbage Collector

    The Boehm-Demers-Weiser conservative C/C++ Garbage Collector

    The Boehm-Demers-Weiser conservative garbage collector can be used as a garbage collecting replacement for C malloc or C++ new. It allows you to allocate memory basically as you normally would, without explicitly deallocating memory that is no longer useful. The collector automatically recycles memory when it determines that it can no longer be otherwise accessed. The collector is also used by a number of programming language implementations that either use C as intermediate code, want to facilitate easier interoperation with C libraries, or just prefer the simple collector interface. ...
